On behalf of the Global WASH Cluster, with funding provided by USAID and ECHO (September-December 2017) and UNICEF (January 2018 onwards), REACH initiated a rapid infrastructure mapping exercise in Rohingya refugee settlements in Cox's Bazar District. This data collection exercise is now concluded, with Round 9 the final round.

The dataset provides the estimated Rohingya refugee population statistics by location (lat/lon), settlement type in Cox's Bazar district, Bangladesh. The dataset is updated regularly. The source is the Needs and Population Monitoring (NPM) in Cox's Bazar.

NPM Bangladesh has produced a number of tools based on its regular data collection activities and drone flights.
SW Map package: for mobile use, this enables users to visualize the site maps and boundaries on their own mobile. Together with the relevant files, users can also find a manual showing step by step how to copy files from their own computer to SW Map running on another portable device.
KMZ file: for desktop use, this enables users to visualize the site maps and boundaries on Google Earth. By adding or removing layers, it is possible to visualize each location assessed by NPM Baseline 10. These files are available on HDX.
Historical UAV imagery of Rohingya settlements in Cox Bazar in GIS, KML Google Earth, Mbtiles (SW Maps), format. Updates of imagery will be added on top of the list.
NPM has also produced individual packages by camps:

The majhee block system represents an important aspect of communities within the Rohingya refugees settled in collective or camp-like settings in Cox's Bazar district. A majhee is a community leader belonging to the Rohingya refugee population, while a block is the area for which he is responsible.
The NPM majhee blocks mapping exercise was first conducted during NPM Baseline 9, between 5 and 20 February 2018. As part of the majhee interview process (key informants), enumerators walked the perimeter of each majhee block with guidance from the KI. As they walked, the field team traced their path, marking up the boundary on the tablet or paper map. Upon returning to NPM office, details of these boundaries were finalized on the paper maps.
The paper maps were then received by the NPM digitizing team. This team carefully digitized the Mahjee zone perimeters in GIS, using high-resolution NPM UAV imagery as an underlying reference. Boundaries were assigned the NPM Block_ID attribute, which represents a unique identifier for each Site Assessment Location. In this manner, boundaries can be uniquely linked back to a mahjee.
The majhee blocks mapping exercise is now embedded in NPM regular assessment activities (baseline and site assessment), hence regularly updated with a frequency of approximately three weeks.
The majhee block system is not an official form of governance. The scope of this exercise is purely descriptive and not prescriptive. Names and boundaries adopted in this exercise do not imply official endorsement or acceptance by IOM.

Data collected in Bangladesh between June-July, 2018. Their analysis contributed to the Xchange Foundation's “The Rohingya Amongst Us”: Bangladeshi Perspectives on the Rohingya Crisis Survey.
The survey sample consisted of 1,697 Bangladeshi adults living in Teknaf (56%) and Ukhia (44%), the two southernmost subdistricts of Cox’s Bazar, and home to the majority of the Rohingya population. The survey was conducted in Bengali with the use of a questionnaire distributed through an online data collection application across more than 71 (up to 97) villages. Respondents were provided with anonymity and verbal consent was ensured before proceeding with each survey. The results of the survey are generalisable to the total adult Bangladeshi population residing in Ukhia and Teknaf upazilas (on a 95% confidence level, the margin of sampling error was 2.37).

Following an outbreak of violence on 25 August 2017 in Rakhine State, Myanmar, a new massive influx of Rohingya refugees to Cox’s Bazar, Bangladesh started in late August 2017. Most of the Rohingya refugees settled in Ukhia and Teknaf Upazilas of Cox’s Bazar, a district bordering Myanmar identified as the main entry area for border crossings.
These datasets present the result of the NPM Round 10 Baseline and Site Assessment exercises, which collected information related to the Rohingya population distribution and needs during the months of April and May 2018.
The data collection for NPM baseline survey was conducted between 1 and 17 April 2018: this provides an update about the population distribution and movements;
The data collection for NPM Site Assessment survey was conducted between 1 and 20 May 2018: in addition to an update about the population figures, this includeds a multi-sectoral needs assessment.

This dataset comprises of 644 facilities that were classified as not exposed to a flood or landslide hazard within the 21 Kutupalong Refugee Camps to assess which facilities would be optimal for further shelter upgrades and reinforcement. An index was created for prioritization and of these 644 sites, 224 were identified as having optimal indicators for further site visits. Corresponding maps for these 224 sites can be found on the REACH Resource Centre or ReliefWeb. It should be noted that ALL 644 facilities not exposed to a flood or landslide hazard should be explored as viable options for awareness raising to the local Camp/Majhee populations. For further information regarding the indicators used for the analysis please see the caveats section below.

This dataset includes WASH infrastructure (latrines and handpump tubewell) exposure to flood and landslide hazards. Data is from REACH's Round 4 infrastructure mapping for Kutupalong Refugee Camps. Flood analysis was conducted by IOM/UNHCR and landslide analysis by ADPC/UNHCR. For access to media hyperlink files please contact reach.mapping@impact-initiatives.org or the ISCG in CXB.
